ASCII 

ESC : 0 0 0 

Hexadecimal  1B 3A 30 30 30 

Decimal 

27 58 0 0 0

Default: 

Current active ROM code page

Copies characters in the active ROM set to RAM. Use this command to re-initialize the user-defined character set. Code 
page 437 is copied by default at initialization. 
This command is ignored if current font is the user font.

To modify characters in one of the character set variations, such as rotated print, select one of the rotated print commands, 
copy to RAM, then use the define user-defined character set command (1B 26).

ASCII 

ESC ? n 

Hexadecimal  1B 3F n 

Decimal 

27 63 n

Value of n: 

Specified character code.

Range of n: 

32–255

Cancels the pattern defined for the character code specified by n. After the user-defined character is canceled, the 
corresponding pattern from current active ROM code page is printed.

This command is ignored if n is out of range or if the user-defined character is not defined.

ASCII 

ESC E n 

Hexadecimal  1B 45 n 

Decimal 

27 69 n

Value of n: 

0 (bit 0) not selected 

 

1 (bit 0) selected

 

(When 0 and 1 are the least  

 

significant bit, LSB)

Range of n: 

0-255

Default: 

0 (Off)

Starts or stops emphasized printing. The printer is reset to the standard print mode after a clear printer (0x10) command is 
received.

Only the lowest bit of n is effective. Emphasized printing cannot be used with bit-images or downloaded bit-images.

This command and the select print mode(s) command (1B 21) function identically. They should have the same setting 
when used together.
In A793 emulation, this command is unrecognized and the parameter byte is put into the print buffer.
